matlabGUI简单的小程序，求解结构的自由振动频率。结合专业，顺便熟悉编程(matlabGUI simple little program to solve the free vibration frequency of the structure. Combined with professional, by the way familiar with the programming)

用MATLAB程序软件完成Z-N法对控制器的参数整定，实现P,PI,PID控制器的分别参数整定，并求出控制器的控制参数Kp，Ti，Td。最后绘制出不同控制器控制下的及参数整定前后的单位阶跃响应图进行比较。(MATLAB program software is used to complete the parameter tuning of the controller by Z-N method. The parameters of P, PI, PID controller are adjusted, and the control parameters of the controller Kp, Ti, Td are obtained. Finally, the unit step response diagram before and after parameter tuning is plotted under different controller control.)

包括最后计算压缩图像的峰值信噪比和压缩效果的源码,计算两个矩阵之间的欧氏距离，IDW距离反比加权方法。( Including the final calculation of the compressed image peak signal to noise ratio and compression of the source, Calculation of the Euclidean distance between the two matrices, IDW inverse distance weighting method.)

fft 快速傅立叶变换，可以进行有效的变换，用于频谱和功率普的分析。(fft)

说明：  通过实验，熟悉Matlab编程环境，学习Matlab的基本使用方法，包括基本的数学运算、图形绘制和编写m文件仿真及使用帮助命令等。(Through the experiment, familiar with the Matlab programming environment, learning the basic use of Matlab, including basic mathematical calculations, graphics rendering and the preparation of m documents and the use of simulation to help orders.)

图像处理程序，内容比较全面，希望对大家有所帮助。(Image processing, the content more comprehensive, we want to help.)

觉得很好的一个Matlab论文想和大家一起分享，互相学习。(Find a good paper would like Matlab to share with everyone, learn from each other.)
